The night sky is different at different times of the year. You see different constellations every now and then. This change is due to the motion of the Earth in its orbit around the Sun. Each day a few stars are visible in the east that were not visible the night before.
Explanation:
Answer:
150°C
Explanation:
T1 = 7.00 C = 7 + 273 = 280 K
V1 = 49.0 ml
V2 = 74.0 ml
T2 = ?
Under constant pressure, V1/T1 = V2/T2, so
T2 = T1 * (V2/V1) = 280 * (74/49) = 423 K = (423 - 273) C = 150 C
The earth spins and rotates on it axis and it will take 2 years to do a full Rotation (I think)
The major product of this reaction which is the oximercuration - demercuration reaction is explained.
<h3>What is a chemical reaction?</h3>

The steps in the reaction include:
- The nucleophilic bond attack.
- The formation of oxonium ion.
- Deprotonation of the oxonium ion.
- NaBH4 replaces the acetoxy mercury.
